commit ea19c8772e70f7c9b2963d8210e50d70a49285bd
Author: Tom Lane <tgl@sss.pgh.pa.us>
Date: Mon Apr 25 20:59:44 2005 +0000
First released in: 8.1.0
get_expr_result_type probably needs to be able to handle OpExpr as well
as FuncExpr, to cover cases where a function returning tuple is invoked
via an operator.
